Why Prime exists
Collecting should feel exciting again.
Buying Pokémon, shoes, and other collectibles at retail has become a contest against professional bots and scalpers. True collectors miss the drop, then face predatory scalper pricing or give up on the products they love.
Prime exists to give everyone a fair shot at MSRP.
A different model
Shopping automation without the bot economy.
Prime
Thousands to own and operate
Free, forever
Dozens of paid proxy clones
Your own Mac and connection
Keys, services, and constant tuning
Install, sign in, start monitoring
A vendor handles sensitive activity
Open source and inspectable
Traditional shopping bots cost thousands of dollars to own and operate. A high-end bot improves one buyer’s odds with dozens of expensive copies. No VPNs, proxies, cloud instances, or proxy clones are needed for Prime. Its advantage is reach: because it is free, far more real collectors can use it.
From restock to receipt
One local agent. The whole purchase.
The complete Prime experience follows a product from inventory signal to confirmed order, with saved evidence at every decision.
-
01
Observe
Watch page-level prices and inventory signals, plus lower-level product data where a retailer exposes it safely.
-
02
Decide
Apply your maximum price, seller policy, variant, quantity, and campaign budget. Save a screenshot when an alert qualifies.
-
03
Cart
Move a verified offer into the retailer cart using the same real browser session you signed into.
-
04
Checkout
Complete the purchase within your rules, retaining a local audit trail from first observation through receipt.
Private by architecture
Real behavior, because it is yours.
Prime doesn’t use VPNs, proxies, or cloud instances. It operates through a browser on your own machine and your own retailer accounts.
Your credentials, purchases, and account history stay private on your machine. Prime does not need a hosted worker to observe or act for you.

Advanced AI, contained on your Mac.
Prime uses advanced AI running locally on your Mac to understand the screen in front of it. It can adapt when a retailer changes a layout, introduces an unfamiliar prompt, or puts something new in the path of your campaign.
- Event A page or inventory signal changes
- Screenshot Prime captures the current visual state
- Local AI On-device reasoning chooses a safe next step
- Verified action Prime acts only within your campaign rules
Event → Screenshot → Local AI → Verified action
This gives Prime a way to navigate unexpected site changes or hurdles without sending screenshots, credentials, or shopping context to a hosted service.
Every action still passes the same price, seller, quantity, and spending rules. If the screen is ambiguous, Prime stops and asks for attention.

Common questions
Built plainly. Explained plainly.
How does Prime decide when to act?
Prime’s complete shopping flow is designed around criteria you define: price, seller, variant, quantity, and budget. It checks page-level and lower-level signals where a retailer exposes them, records a matching offer with screenshots and evidence, and carries that verified offer through carting and checkout.
Do I need Chrome, an extension, or API keys?
No. The macOS app includes its browser runtime. Install Prime, connect a retailer from Settings, sign in when needed, and create a campaign.
Why is Prime free?
The mission is broader access for collectors. An open-source tool that anyone can run gives more people a chance to buy at retail without paying for an expensive bot or proxy fleet.
Does Prime guarantee a purchase?
No. Inventory can disappear quickly, retailer behavior can change, and a matching alert does not guarantee an item will still be available at checkout. Prime is designed to react quickly and keep clear evidence of what it observed and did.
Ready for your next restock?
Prime is designed to bring your buying rules and the entire shopping journey onto your own Mac, from the first signal to the receipt.
